Embodiment 1
[0036] (a) 1.2 g of MWNTs with a diameter of 30-50 nm and a length of 15 μm were mixed with 120 ml of concentrated nitric acid, ultrasonically oscillated for 10 minutes, and reacted under reflux at 70° C. for 24 hours. After the mixture was cooled, it was diluted with distilled water, vacuum-filtered with a cellulose membrane (pore size 0.45 μm) until the pH value of the filtrate was neutral, and the filter cake was vacuum-dried at 60° C. for 12 hours.
[0037] (b) Mix 1gM WNTs-COOH obtained in the first step with 40ml SOCl 2 Reflux and stir at 65°C for 24 hours. After cooling, the reaction mixture was diluted with anhydrous tetrahydrofuran, filtered through a polyvinylidene fluoride membrane (pore size 0.45 μm), repeated three times, and dried in vacuum at room temperature for 2 hours.
[0038] (c) 1 g of MWNTs-COCl after vacuum drying and 10 g of polycaprolactone were stirred and reacted in 10 mL of 1,2-dichlorobenzene at 120° C. for 60 hours. Wash with hot absolute ethanol...
Embodiment 2
[0041] (a) 1.2 g of MWNTs with a tube diameter of 8-15 nm and a length of 50 μm were mixed with 120 ml of concentrated nitric acid, ultrasonically oscillated for 10 minutes, and reacted under reflux at 70° C. for 24 hours. After the mixture was cooled, it was diluted with distilled water, vacuum-filtered with a cellulose membrane (pore size 0.45 μm) until the pH value of the filtrate was neutral, and the filter cake was vacuum-dried at 60° C. for 12 hours.
[0042] (b) Mix 1gMWNTs-COOH obtained in the first step with 40ml SOCl 2 Reflux and stir at 65°C for 24 hours. After cooling, the reaction mixture was diluted with anhydrous tetrahydrofuran, filtered through a polypropylene filter (pore size 0.45 μm), repeated three times, and vacuum-dried at room temperature for 2 hours.
[0043] (c) 1 g of MWNTs-COCl after vacuum drying and 10 g of polycaprolactone were stirred and reacted in 10 mL of 1,2-dichlorobenzene at 120° C. for 60 hours. Wash with hot absolute ethanol, and suctio...
Embodiment 3
[0046](a) 1.2 g of MWNTs with a diameter of 30-50 nm and a length of 15 μm were mixed with 120 ml of concentrated nitric acid, ultrasonically oscillated for 5 minutes, and reacted under reflux at 70° C. for 24 hours. After the mixture was cooled, it was diluted with distilled water, vacuum-filtered with a cellulose membrane (pore size 0.45 μm) until the pH value of the filtrate was neutral, and the filter cake was vacuum-dried at 60° C. for 12 hours.
[0047] (b) Mix 1g MWNTs-COOH obtained in the first step with 40ml SOCl 2 Reflux and stir at 65°C for 24 hours, dilute the reaction mixture with anhydrous tetrahydrofuran after cooling, and suction filter with a polyvinylidene fluoride filter membrane (pore size 0.8 μm), repeat this process 3 times, and vacuum dry at room temperature for 2 hours.
[0048] (c) 1 g of MWNTs-COCl after vacuum drying and 10 g of polycaprolactone were stirred and reacted in 10 mL of THF at 70 °C for 19 hours. Wash with hot absolute ethanol, and sucti...
